I was trying to use the 'network' tab on Chrome's dev settings to download a YouTube video, but it is broken into many parts. Is there a good way to get this video without having to install a program? I even used a chrome extension, but it still showed the video in many parts, the same way I see it under 'network' tab.

I have found that lowering the resolution can sometimes help, but only with firefox so far. I have been able to easily download 'one hour plus' length videos in firefox with or without 3rd party plugins, but not in chrome.

I don't understand the question - based upon your title I suggests you download each part and then use a program to add them together then render out when complete.

I can see how that is unclear. What I meant is that a video that on youtube is superficially one stream, appears as multiple different .flv files in the 'network' tab of dev settings. The video content is seeming to be delivered in many parts as opposed to one .flv that I can download.

Are you sure you aren't seeing the main video, and then an advertisement or two?
